9 Claims.

This invention relates to certain new and useful improvements in coin-controlled devices adapted for use with coin-operated machines, such for example as phonographs, in which a predetermined number of records may be played upon the deposit of one or more coins.

It has for one of its objects to provide a coincontrolled device which is so designed and constructed as to function with coins of different denominations, say five and twenty-five cent pieces.

Another object of the invention is to provide a coin-controlled device of this character designed. for use in conjunction with a magazine switch device and wherein the coin-controlled device mechanically controls the actuation of the magazine switch device to thereby properly register and govern the magazine switch in accordance with the coin-value deposited.

A further object is to provide a coin-controlled device of this character with means for adjusting the throw of one of the magazine controlling levers, thus permitting the coin-controlled device to be readily adaptable to operate with coins of different denominations, say, five, ten and twenty-five cent pieces.

A still further object of the invent-ion is to provide a coin-controlled device which is simple, compact andinexpensive in construction, which is positive and efilcient in operation and whose parts are not liable to get out of order.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 6 is a fragmentary transverse vertical section line 88, Figure 7. Figure 9 is a iragmentar distended perspective view of the switch-controlling ratchet wheels and their associated pawls.

Similar characters of reference indicate corresponding parts throughout the several views.

While my coin-controlled device is applicable for use with various types of coin-operated machines, it has been designed more particularly for use on automatic phonographs which employ magazine switch mechanism for registering the coins deposited and which assure the playing of as many records as there are coins or coin-values deposited. In its general organization, it consists of the usual and well known coin-advancing slides, two being shown side by side as a complete unit on a suitable frame or support, for receiving, say, five and twenty-five cent pieces, respectively; mechanical means controlled by the respective coin slides for individually controlling the magazine switch mechanism in accordance with the value and number of coins deposited to maintain the circuit of the phonograph closed until the proper number of records have been played for the coins or coin-value deposited; and a resetting mechanism actuated by a moving part of the phonograph and operatively connected to the magazine switch mechanism for opening the magazine switch to thereby open the circuit of the phonograph and restore the parts to their normal position.

Referring now to the drawings, the numeral l0 indicates the chassis of a phonograph upon Which the working parts of my invention are mounted. Suitably mounted in a frame or support is a unit of, coin slides indicated generally at H of well known construction to accommodate, say, five and twenty-five cent coins, the advancing slides of the unit being indicated at [2 and 13, respectively. In Figure 1 there is shown a portion of the operating mechanism of an automatic selective phonograph which, however, forms no part of the present invention.

Mounted on a plate 14 secured to the chassisbase are a plurality of coin-slide controlled mechanisms, two being shown in the drawings and indicated generally at [5 and [6 for actuation by the five and twenty-five cent coin slides l2 and i3, respectively, for in turn individually governing the magazine switch mechanism. These slide-actuated mechanisms are identical in construction and a description of one of them will suffice for both. This mechanism consists of superposed, horizontally-swinging control arms or levers ll, 18 pivoted to swing about a common pivot I9 mounted on the plate l4 below the plane of travel of the coin slides. Rising from adjacent the outer end of the top lever 18 is a post or pin 20 which is disposed normally in the sliding plane or path of the companion coin slide I2 or l3 .to be actuated thereby to swing said levers l1, E8 to a position for controlling the magazine switch mechanism in accordance with the value 7 or number of coins deposited in the coin slide. These levers are normally latched to swing jointly when advanced by a respective coin slide and a spring 2! constantly urges the lever 18 to a retracted position, shown in Figure 1, when the coin slide is retracted aiterdischarging a coin. Pivoted at 22 to the lever is is a trip arm or latch 23 having a finger 24 at one end which normally abuts or latches behind an upstanding shoulder formed on the control lever H, as shown in Figure 2 in connection with the slide I2, and at its other end the latch has a spring 26 connected thereto which urges it against the post 29 rising from the lever is. In advancing the coin slide H2 or 13 to its coin-discharging station, the slide strikes the post 25 of the correspondin control lever 58 andswings it and the companion latched lever 'i iahout the pivot I9 as a unit from the dotted line to the full line position shown in Figure 2 in connection 'with the slide [3, and as the partsjnear the end of the stroke, as seen by full lines in Figure'o, the finger 2d of the latch '23 is released from the shoulder 25 or" the lever 'l l through'the medium of a cam' finger 2] formed on the latch 'andstriking a tapp'et-pin 28 arranged in its forwar path and rising from the plate is, thus automatically unlatching and releasing the lever i! 'from the c'ornpanion'lever i8 and permitting the free and independent return ofsaid lever H to its initial position in the manner which will 'liere'afte'r appear. Upon the retraction of the coin slide to its initial position preparatory to inserting another coin, the lever is follows back with it under the pressure of its spring 2i and the latch 23 is automatically restored to its latched position behind the shoulder 2501 the lever 17 by the spring 2t, thereby resetting these'parts for the next coin slide operation.

A coin register and magazine switch'Zi-J of the micro or like type is included in the circuit of the phonograph or other instrumentand is rendered operative in response to the coin slide controlled mechanisms i5 and it to eiiect the closing of th'is switch, the latter remaining closed over a predetermined period in accordance with the number or value of the coins deposited i'n'the coin slides. This switch'includes a fixed contact 33 and a spring press'ed movable contact 3i adapted to be actuated by a rock arm 32 to effect the opening and closing of the switch. 'Asshown in Figure '1, these contactsare connected to the means ofthe phonograph. Loosely mounted on an upright'shaft 3 4 fixed to the chassis H] of the phonograph adjacent the switch'zg are superpos'ed ratchet wheels 55 andtfi' disposed in'spaced relation, as seenin 'Figures'3 and 7. Borne by and'piv'otedatfis' to the underside of the'lowr ratchet wheeltt is a switch-governing element 38 which is shaped intermediate its ends to freely straddle or e'mbrace the shaft as and is free to be displaced about its pivot'in a direction axially of the'shait. 'Ihe'intermediateportion of this switch-governing element is adapted through the medium 7, of an interposed washer 39 to abut against the free end of the switch-actuatingarm "BZQWhe e'by when the element 38 is displacedin a direction away from the'ratchet wheel, asseen by dotted lines in Figure 7, it serves'to open the switch 29, and when shifted in the opposite direction by spring pressure to the full line position seen in the same figure, the switch is automatically closed. As shown in Figure '7, the springpressed switch contact 3| tends constantly to seek a closed position, and this also tends to rock the arm 32 and switch-governing element 33 to the full line position shown in such figure. At its free end the switch-governing element 33 is provided with an upwardly-extending lug do which passes freely through an opening il in the lower ratchet wheel 36, the terminal end of this lug being beveled or pointed as indicated at 62 in Figure 8. Mounted on the upper ratchet wheel 35 in opposing relation to and for predetermined cooperative engagement with the beveled end of the lug 48 of the switch-governing element 38, is a tooth or projection 43 which, during relative movements of the ratchet wheels 35 and 35, in one instance, contacts said lug All to displace the switch-governing element 38 to switch-opening position and which, in another instance, is released from such contact to permit the automatic displacement of such element to switchclosing position. The ratchet wheels are mounted for independent rotation in a counter-clockwise directiom'the upper wheel 35 being adapted to be actuated one step or'o'ne tooth for each five cent coinvalue deposited in one or the other of the coin slides 12, i3 during which time the'companion or lower ratchet wheel 3% is stationary, and for each five cent coin value deposited the upper wheel 35 withits tooth or projection 43 progresses or recedes step by step away from the lug so of the'companion switch-governing element, thereby registering the coin value and maintainingthe circuit of the phonograph closed as determined by the coin value deposited. After each record is played on'the phonograph, a moving part thereof functions to transmit a step by step counter-clockwise movement to the lower ratchet wheel 36 while the companion ratchet wheel 35 remains stationaryso that eventually, after the playing of the last record of the numher to be played for the coin value deposited, the beveled lug 4B of the switch governing element 38 will contact and ride beneath the companion tooth'43 of the upper-ratchet wheel 35 and cause th'e'displa'cement of such element to in turn rock the arm 32 to open the switch 29.

The counter-clockwise movement of the upper or coin-registering ratchet wheel 35 is mechanically controlled from one or the other of the mechanisms, IE, IS associated with the five and twenty-five cent coin slides 12 and i3, respectively, so that for every five cent coindeposited the ratchet wheel 35 will be advanced one tooth and for every twenty-five cent coin deposited the ratchet wheel will be advanced five teeth to accordingly close the switch 29 which thereupon remains-closed until the last record for the coin value deposited has been played. For this purpose there is associated with the control lever -l? of the five cent coin control mechanism, a reciprocating bar or link so pivoted at one end, as indicated at so, to such lever, and having at its other end a spring-urged pivoted dog do. A

spring '67 connected to this reciprocating bar constantly ten'dsto urge said bar to a retracted or effective operating position shown by dotted lines in Figure 5, while aspring :38 connected to the dog 46 urges the latter against a stop 49 applied to the base IL. Disposed at substantially 'right anglesto the'reciprocating bar 44 in end- -wise'cooperativeengagement with the dog 45 is a rock lever 50 pivoted intermediate its ends at to the base It and provided at its other end with a pin 52 which extends upwardly through an arcuate slot 53 formed in the base If), said pin normally abutting a spring-urged arm 54 pivoted at 55 to an adjoining bracket plate 56 on which the shaft 34 and associated parts are mounted. A spring 50 tends to urge the rock lever 50 to its full line position seen in Figure 5. This arm 54 is provided with a spring-pressed feed pawl 51 which engages the upper ratchet wheel 35 for turning it in a counter-clockwise direction in a step by step fashion. Upon the advancement of the coin slide l2, the bar 44 will be correspondingly advanced idly and the dog 46 will ultimately ride off the end of the rock lever 50 and be projected by its spring 48 into the path of the shouldered portions 58 of such lever, so that upon the return of the bar 44 to its operative retracted position by its spring 41, after the completion of the advancing stroke of the coin slide and the subsequent unlatching of the control lever I! from the companion lever i8 by the tappet 28, said dog 46 will trip the rock lever 59 and swing it from the full line to the dotted line position, shown in Figure 5, with the result that the feed pawl 51 will advance the ratchet wheel 35 one tooth.

In order to advance the coin-registering ratchet wheel 35 five teeth when a twenty-five cent coin is deposited in the coin slide 13, I provide a reciprocating bar or link 59 which is pivoted at one end at 60 to the control lever I! of the mechanism associated with the coin slide 13, while its opposite end is pivotally connected to one arm of a rock lever 6| pivoted intermediate its ends at 52 to the base It! and provided at its opposite end with a link 63 connected to one arm of a lever 6-4 loosely or pivotally mounted on the lower end of the ratchet wheel shaft 34. On its other arm this lever 54 carries a spring-pressed feed pawl 55 cooperating with the ratchet 35. A spring 55 connected tothis pawl-carrying lever tends constantly to urge this lever and its associated parts including the reciprocating bar 59 and companion lever i! from the full line to the dotted line position seen in Figure 2. By this construction, when the coin slide I3 is advanced the corresponding control mechanism I5 is actuated to in turn swing the lever 64 in a clockwise direction from the dotted line to the full line position shown in Figure 2. During this time the feed pawl 55 merely ratchets clockwise over five teeth of the wheel 35, and upon the completion of the advancing stroke of the coin slide the spring 55 restores the parts to their normal positions, the feed pawl at the same time actuating the ratchet wheel in a ccunterclockwise direction a distance of five teeth.

A spring-pressed, duplex pawl 55? may be pro vided for engagement with both ratchet wheels 35, 36 to constitute a forward and backward stop for such wheels.

For the purpose of eifecting the counter-clockwise movement of the lower ratchet wheel 36 to restore the switch 23 to its open position after the patron has received the playing of records corresponding to the coin value deposited, I provide a feed pawl 58 which is connected by a screw 59 and slot "it! to the bracket plate 53 for combined pivotal and sliding movement relative to the ratchet wheel. A spring H normally urges this pawl to swing in a direction toward the periphery of the wheel. This pawl is disposed for actuation to move the ratchet wheel 36 counterclockwise a distance of one tooth by a moving part of the phonograph, say the gear wheel 12 associated with the record-changing mechanism. To this end this gear has a lug 13 thereon which at a predetermined time engages the end of the pawl and shifts it in a direction to turn the ratchet wheel one tooth, thereby moving the switch-governing element 38, 40 carried by it in a direction toward the tooth 43 on the coinregistering ratchet wheel 35. With each playing cycle of the phonograph the wheel 35 is moved in a step by step fashion until the lug 43 of the switch-governing element registers with the companion tooth 43 of the wheel 35, at which time the switch 29 will be automatically opened, indicating that the last record for the coin vlalue deposited has been played.

If it be desired to employ this mechanism in connection with a remote control coin slide, a magnet 14 may be mounted on the plate 55 adjoining the five cent control pawl 5'! and the carrying arm 5-4 of the latter may be provided with an armature 15, so that upon energizing the magnet the pawl is actuated to move the ratchet wheel 35 one step for each coin deposited.

Means are provided for adjusting the eifective movement transmitted by the feed pawl 55 to the coin-registering ratchet 35, whereby a coin of different denomination may be used in the coin slide 53 and whereby a more or less number of records may be played, for the coin used. For this purpose I provide an adjustable cam plate 16 mounted on the shaft 34 in overlying relation to the upper ratchet wheel and adapted to be secured thereon in an adjusted set position by a screw Ti. This plate is shaped to provide an edge contour 18 which is disposed within the pitch circle of the ratchet teeth of the wheel 35 so as to not interfere with the normal engage ment of the pawl 55. As shown in Figure 3, the tooth-engaging end or lug T9 of this pawl is of a length to extend over the peripheral edge of the cam plate. At its outer end the cam plate has a portion 8!] which extends over the adjoining toothed portion of the wheel to block out the teeth thereof from engagement by the feed pawl. As seen in Figures 1 and 2 of the drawings, the cam plate 76 is set to effect a pawl-ratcheting stroke of five teeth for registering five record plays for each twenty-five cent coin deposited. Should it be desired, for example, to substitute a ten cent coin slide for the twenty-five cent slide, then the cam plate is adjusted in a clockwise direction to block out, say three teeth of the normally exposed five teeth of the ratchet wheel 35, so that for a portion of its initial or presetting travel in a clockwise direction the pawl 55 rides over the edge of the cam plate portion 3!! a distance equal to three teeth and then ratchets over two of the exposed teeth for the balance of its stroke. On the return or effective counter-clockwise stroke of the pawl 55, the ratchet wheel will be moved in a like direction a distance of two teeth, and for the balance of its return stroke the pawl will encounter the cam portion 80 and be lifted from the ratchet teeth and merely slide idly to its initial or starting position over a distance of three teeth as determined by the stroke of the coin-slide actuated bar 59. Should it be desired that the patron receive three records plays for ten cents, then the cam plate is accordingly adjusted to block out all 'but three teeth of the normally exposed five teeth of the ratchet wheel 35.

Briefly, the operation of this coin-controlled mechanism is as follows:

Assume that the mechanism is applied to an automatic coin-controlled phonograph and the patron at five cents per record, desires to play six records and after making his selections at the phonograph, places a nickel in the slide [2 and a quarter in the slide I3. Upon advancing the slide i2, the ratchet mechanism 35, 52', through the slide-actuated mechanism l and intermediate parts 34, 48, 50 and 54, is advanced one tooth in a counter-clockwise direction and accordingly the lug 43 on the ratchet wheel 35 moves away a distance of one tooth from the tapered end it of the switch-governing element 33, thereby closing the magazine switch 29 and rendering the phonograph operative. Upon advancing the twenty-five cent slide l3, the ratchet mechanism 35, 65 is advanced five teeth in the same direction and in a like manner through the slide-actuated mechanism mediate parts 5 5, 61, 63 and E i, and the lug 33 on the wheel 35 is accordingly moved the same, distance away from the tapered end of the switch-actuating element 38. After each record is played the gear i2 having the lug l3 thereon, strikes the pawl 63 which engages the wheel 35 and likewise moves it in a countor-clockwise direction one tooth at a time until the tapered end it of the switch element 38. rides under or contacts the lug 33, on the ratchet wheel 35, at which time the magazine switch 29 is automatically opened. Upon the deposit of another coin in any one of the coin slides, the ratchet wheel 35 and lug ii? move away from the switch-governing element 38, 49 to automatically eiiect the closing of the switch 29. and start the phonograph playing.

Should a patron insert, during a given time interval, more coins or coin values than correspond to the number of teeth on the companion switch control ratchet wheels 35, 3%, provision is made to prevent the opening of the switch 29 at'a predetermined time in the relative cpin registering movements of the wheel 35, as for example, when the latter makes a com.- riete v t n' d he 1 t ap r s a position adjoining the tapered end 2 of the switch-actuating element 38 To this end, as shown in Figure 9, I provide a stoppin 8 rising i6 and intercontrolling part, a plurality of feed pawls operativelyassociated with one of said ratchet wheels d am s t i feren p edet r ine tances to cause a displacement of the element borne thereto to a switch-closing position, means operatively connected to said'feed pawls for independently actuating said pawls to advance said last-named wheel predetermined distances and means for actuating said other ratchet wheel at predetermined times to advance it'relatively to the companion ratchet wheel in a direction to cause the element borne thereby to displace the companion switch-governing element to a switch-opening position.

This stop is disposed in the counter clockwise path or travel of the lug {53 on the coin-registering wheel 35' to prevent that lug from conta'cting and tripping the switch-actuating element should that wheel be advanced to that extent; When contact of the lug $3 is made with the pin 8!, and coins are thereafter inserted in the coin slides, then both wheels 35, 35 are propelled in unison to properly register the coin'value.
